new grow. need input!!!

My last grow i grew in a grow tent. we currently moved and i had to sale the damn tent due to limited space. now i have a closet. about 2x4x5. i want to use half of it to grow but i have no clue how to start.

My current idea.... set up a 250watt hps and grow about 15small dwarfs in those double big gulp cups. I need help making half the closet completely light proof. Any ideas? and where can i find a door for this closet or should i make 1???

Shit if I lived there we'd figure something out... Wutever lights u wnt hangin.. Put up a trellis or do sumthng to keep the plants short... THermal sheild/Mylar..... Something to cover that space up.. One time lol I used a trashbag wit therm shield taped up to it n it was like a tent... Ghetto ass shit but it dude look ight lmao... K.O.double g cuz... King of ghettogrow hah!... I know u can come up wit something cuz...

Make a closet door.. I forget wut other material u can use... It's on a grow video on YouTube... Some kinda sheet lookin thing.. It's the vids with that green pInted mellow dude He grows it hydro...check it out... I grow chronic something likethat.. Ur plan sounds ight bro

Im tripping on space. i wana grow short bushy plants nothing tall. where can i find dwarf seeds?? im measuring the exterior of door right now so i can find a door for it. ima divide the closet with another board of wood too. what about temps u think they will be high???

Jusnhavd proper venting and it won't be too hot... Not over 82 85 that pushing it... Sum plants can take it sum cnt.. Few of mines did when I first started... High temps in lil boxes... 86 one time... Jus gotta vent it.. Red dwarf n white dwarf..lowrider... Taiga... Any autoflowers... Wut seedbanks u like or have heard of or seen wutevr... Look up in the search engine worldwide.. U heard of it? Ima bout to crash I think homie... My girl jus hit me n said to get off this shit lol... Had to check her real quik.... Lol.. Nah man find out bout that site.. Worldwide...

If i get an auto-flowering strain do i have to switch to 12/12 or can i keep it on a vegg cycle??
